3 Background theory: Thermal Wind and Margules relation
Figure 3.1: After the can is removed from the tank, the bottom of the dense fluid moves outwards, forming a cone. The less dense fluid converges towards the center of the tank, spiraling cyclonically in order to preserve angular momentum. The dense fluid spreads outwards, spiraling anti-cyclonically in order to preserve its angular momentum.-

In order to collect data from our experiment, we tracked using video processing software buoyant particles at the surface of the fluid, as well as particles with density in between that of the two fluids which sat just above the frontal boundary. The shape of the front, although relatively stable, did vary slightly throughout the course of the experiment, as can be seen from the following images.
